“We’re very excited to be writing. We will be going into a cave for months to finish. An actual cave. We found one that’s nice and big. We’re putting a couch in there,” a statement from Wiig and Mumolo said.

Wiig and Mumolo were nominated for a best original screenplay Oscar for the 2011 comedy Bridesmaids, which they co-wrote. The raunchy film, about a dysfunctional group of bridesmaids, was directed by Paul Feig and earned a stellar $288.4 million worldwide.

Mumolo recently wrote the Joy Mangano story for Fox 2000, which will be directed by David O. Russell and star Jennifer Lawrence. Her acting credits include the Judd Apatow-directed This Is 40 and the Sundance Award-winner Afternoon Delight. Recently recurring on NBC series About a Boy, Mumolo is repped by UTA, Thruline Entertainment and Jackoway Tyerman.

Former SNL star Wiig more recently appeared in The Secret Life of Walter Mitty, Anchorman 2 and Hateship Loveship as well as voice work in the Despicable Me and How to Train Your Dragon franchises. She’ll next be seen in The Skeleton Twins, and is repped by UTA, Odenkirk Provissiero Entertainment and Jackoway Tyerman.

“Kristen and Annie assured me that the film will be a searing and depressing drama, which is what the world needs right now. So we grabbed it. Perhaps more to the point, these two supremely talented ladies are always ahead of the comedy curve, and as we at TriStar push for originality, we are lucky as hell to be in business with them,” said Rothman. “The chance to hopefully make Kristen’s first film as a director is the cherry on top.”
